Celestial Log

NASA Observation

When two black holes collide, they release massive amounts of energy in the form of gravitational waves that last a fraction of a second and can be "heard" throughout the universe - if you have the right instruments. Today we learned that the #LIGO project heard the telltale chirp of black holes colliding, fulfilling Einstein's General Theory of Relativity. NASA's LISA mission will look for direct evidence of gravitational waves. go.nasa.gov/23ZbqoE This video illustrates what that collision might look like.

Stargazer FAQ

Are the colors in this nebula image real?

NASA often uses 'false color' techniques. Scientists map invisible wavelengths (like infrared) or specific gases to visible colors (red, green, blue) to highlight the nebula's structural details.

Can I see this nebula with a standard telescope?

While some bright nebulas are visible with entry-level telescopes, capturing these stunning details usually requires deep-sky astrophotography equipment and long exposures.
